Too simple to be a complex type, too complex to be a simple attribute. That鈥檚 what tuples in C# are. Perfect for returning multiple values from a method. No need to create a class (or even a record). Easy to read. Take a look at the image post and see how to use it. Do you use tuples, or do you prefer DTOs/records? 馃憠 Adapted from my original post on LinkedIn . ...
In C#, implicit operators enable automatic type conversions without the need for explicit casting. This functionality not only enhances code readability but also boosts development agility while safeguarding against runtime conversion exceptions. However, be careful. While implicit conversions offer convenience, excessive usage can potentially compromise code clarity. It鈥檚 essential to tread carefully as an overreliance on implicit conversions may obscure the precise moments and locations where conversions occur. 馃憠 Adapted from my original post on LinkedIn . ...
Convert a foreach loop to LINQ LINQ transforms a query into a first-class language construct in C#. It can reduce the amount of code, enhance readability, and enable similar query expression patterns across different data sources. 馃憠 Adapted from my original post on LinkedIn .
Comparing Numbers with Tolerance in C# Sometimes, when comparing two numbers in C#, you may want to allow for a tolerance or interval in the comparison. Instead of manually adding, subtracting, and comparing the values, you can use Math.Abs on the difference between the two numbers to check if the result falls within your acceptable range. 馃憠 Adapted from my original post on LinkedIn .
TempData - Transfer data between controllers Ideal for transferring small amounts of data between controllers in ASP.NET MVC. Unlike ViewData and ViewBag, which are specific to a single view, TempData persists for one request cycle. This means the data remains available until it鈥檚 accessed, at which point it鈥檚 automatically removed. 馃憠 Adapted from my original post on LinkedIn .
Concerned about duplicate URLs in ASP.NET MVC? Take care of both www and non-www domains. .NET already provides the correct method to handle them. Using the UseRewriter middleware is the optimal approach. You can use AddRedirectToNonWww() or AddRedirectToWww() for this purpose. 馃憠 Adapted from my original post on LinkedIn .
Accessing Custom Attributes Using Reflection in C# Custom attributes provide a powerful way to attach declarative metadata to your code-whether it鈥檚 on classes, methods, properties, or fields. But how do you actually read that metadata at runtime? This is where Reflection shines. By using the System.Reflection, you can dynamically inspect your code鈥檚 structure and retrieve the information defined within those custom attributes. This functionality is the backbone for creating highly flexible applications, such as automated validation frameworks, custom JSON serializers, or dynamic API routing systems. ...
Pattern Matching: Get Protected from Nulls C# pattern matching provides a substantially more concise syntax for testing expressions and taking decisive action when an expression matches. By leveraging these structural features, you can gracefully bundle type checks, variable declarations, and null validations into a single, highly readable statement-significantly reducing boilerplate code and the risk of unexpected NullReferenceExceptions. 馃憠 Adapted from my original post on LinkedIn .
Using Regular Expressions (Regex) is a highly effective method for segmenting your ASP.NET MVC routing. With Regex route constraints, developers can create intricate matching patterns, leading to much more flexible and dynamic routing configurations directly in their controllers. Important: Always exercise caution when using System.Text.RegularExpressions to process untrusted input, as poorly constructed patterns can be vulnerable to Regular Expression Denial of Service (ReDoS) attacks. 馃憠 Adapted from my original post on LinkedIn . ...
